Abstract

Abstract

The effect of pressure on quenching process of commercial pure titanium (CPTi) has been studied.Annealed, water quenched and high temperature and high pressure (HTHP) treated samples were prepared for comparison. The phase composition and microstructure were analyzed, and the microhardness was measured. Results showed that under high pressure quenching, specimens were all α-Ti martensite, and the grain refinement and microhardness were increased with the increasing pressure. For the pressure treated sample, there was no elevation on hardness compared with water quenched sample. Besides, the elongation of water quenched specimen was quite lower than that of the as-received sample. Herein, to investigate the ductility and tensile strength, tensile test was carried out by using samples treated by self-heating process under high pressure. The data showed that the strength of the treated sample was substantially promoted and the ductility was good, which was close to as-received sample.
